Trombe wall

Trombe wall

noun

A thick, usually masonry wall faced with glass or other transparent material over an intervening air space, designed to absorb solar radiation and release heat slowly to the air, which circulates throughout the building by convection.

A wall built on the winter sun side of a building with a glass external layer and a high mass internal layer separated by a layer of air, so as to absorb heat during sunlit hours of winter and slowly release it overnight.
